If the @ and “ keys on your keyboard have suddenly switched places, there’s a simple fix.
This has happened because a recent Windows 10 update changed the default language and region settings to US English.
To fix it, click the Windows button in the far left hand corner of your taskbar (or tap the Windows key on your keyboard) and start typing “Region & language settings”.
Click on that to go to the Region & language page of Settings.
Under Languages, check to see if English (United Kingdom) is listed.
If not, click the Add a language button, then scroll down to English in the list of languages and click on English.
If you're adding a new language pack, be warned: it will take a few minutes to download
Once you’ve done that, you’ll be taken back to the Region & language screen. Make sure that English (United Kingdom) is at the top. If it’s not, move it to to the top by clicking on the arrows.
You can quickly check which version of English your keyboard is using by looking in the system tray of your taskbar – that’s the area at the right-hand end of the taskbar.
Click on ENG (next to the date and time) and the pop-up box will show you which version you’re using. If it’s switched to another language, click to change it.
